What is ARPT on Airbus A320? (Airport)

The Airbus A320 is a narrow-body, twin-engine aircraft developed by Airbus. With its sleek design and advanced technology, the A320 has become one of the most popular choices for airlines worldwide. As part of its innovative features, the A320 includes an Airport (ARPT) system that plays a crucial role in ensuring a safe and efficient flight experience for both pilots and passengers.

Now, you may be wondering, what exactly is the Airport system on the Airbus A320? Let’s dive deeper into this important component and explore its functions, features, and benefits.

How Does the Airport System Work?

The Airport system on the Airbus A320 is an integrated package of avionics systems that provides valuable information to the pilots during various phases of flight. It consists of several sub-components, including the Airport Control Unit (ACU), Airport Display Unit (ADU), and Flight Augmentation Computer (FAC).

The ACU serves as the central hub of the Airport system, receiving data from various sensors and systems on the aircraft. It processes and interprets this information, allowing the pilots to have a comprehensive understanding of the aircraft’s behavior and performance throughout the flight.

The ADU, on the other hand, provides pilots with visual displays of important flight parameters and system status. It presents this information in an easy-to-read format, allowing pilots to quickly assess the situation and make informed decisions.

The FAC is responsible for continuously monitoring the aircraft’s flight controls and providing necessary inputs to ensure stable and precise flight. It enhances the aircraft’s handling qualities, reduces the workload on the pilots, and improves overall safety.

Overall, the Airport system functions as a comprehensive information and control center, allowing pilots to have real-time data and precise control over the aircraft’s behavior.

Benefits of the Airport System

The Airport system on the Airbus A320 offers several benefits that contribute to the overall safety and efficiency of the aircraft. Let’s take a closer look at some of these advantages:

1. Enhanced Situational Awareness: The Airport system provides pilots with critical information about the aircraft’s position, speed, altitude, and other flight parameters. This enables them to have a better understanding of the overall flight environment, improving situational awareness and decision-making capabilities.

2. Precise Flight Control: With the help of the Airport system, pilots can achieve precise control over the aircraft’s flight path and behavior. The system continuously monitors the aircraft’s flight controls and provides necessary inputs to ensure stability and responsiveness, enhancing the overall flying experience.

3. Automation and Efficiency: The Airport system automates various tasks and calculations, reducing the workload on the pilots and enhancing overall operational efficiency. It streamlines the flight operations, allowing pilots to focus on critical decision-making and maintaining a smooth flight.

4. Enhanced Safety: The Airport system plays a vital role in ensuring the safety of the aircraft and its occupants. It provides real-time data and alerts about any abnormalities or malfunctions, allowing pilots to take immediate corrective actions. This contributes to the overall safety and reliability of the Airbus A320.


The Airport system on the Airbus A320 is a critical component that enhances the aircraft’s overall safety, efficiency, and performance. It provides pilots with real-time data, precise control, and enhanced situational awareness, allowing for a safe and enjoyable flight experience. With its innovative features and advanced technology, the Airport system on the Airbus A320 continues to set new standards in the aviation industry.
